TOPEKA, Kan. (AP) — An agreement arising from a fatal natural gas explosion in Topeka will fine one company and require another company to change its operations.

The Kansas Corporation Commission on Wednesday approved the agreement in response to a January 2012 explosion that killed 81-year-old Lucinia Tolliver at her home.

The Topeka Capital Journal reports (http://bit.ly/11gFiML ) the agreement fines N-Line Lawn Service $5,000. The company was installing a sprinkler system in a yard behind Tolliver’s home when one of its machines moved a Kansas Gas Service line.

Kansas Gas Service will be required to make such changes as amending its emergency plan, revising its training and identify areas where gas mains and sanitary sewers are close together. However, the utility will not be fined.
